I can solve one and two-step inequalities

Review of Inequalities

Review of One/Two-Step Equations Solving inequalities is almost the same as __________________________________. Why?

INVERSE OPERATIONS!

So what’s the difference?

Inequalities can have ___________________ ____________________________________. For example: 2x + 8 > 20 X > 6, means that any number bigger than __ can be a _______________.

With inequalities, you flip the inequality sign (, ) when you: ____________ by a negative number – Switch signs of the equation -2x > 4 would become -2 < x

True or False? When you get the answer put your fist in the air! When I count to 3…give me a 1 for True and 2 for False. TRUE OR FALSE? An inequality has more than one solution.

What does this look like in real life? The high school soccer team can have no more than 26 players. Write and solve an inequality to determine how many more players can make the team if the coach has already chosen 17 players x < 26 My solution means:

Practice 1)6x > 24 2) 1 + (-8x) < 17

Coach and Scribe You will work with your partner or partners to complete the Coach and Scribe activity. 1 person will be the coach and 1 person will be the scribe. The coach is the only one speaking, and tells the scribe exactly what to write to solve the problem. The scribe writes down the solution step by step. Check off the correct items in the left column. BOTH PARTNERS MUST AGREE ON THE ANSWER!! Switch roles for the next problem.

How Far Can You Go? Work independently and silently at your desk. Level 1 problems are less advanced than Level 2. If you would like to check your answers, raise your hand and I will come to your desk.
